`The dov/el pins 33- areplaced in and `profitent fif'om' the footing 38 butthey are not positioned with any accuracy, therein. `In general they` are placed along a lineapproxirnating the' center of the footing" 38. When the member 3|] is plaoed over the dov/'el pin `33 the members 24 and 2`5 are free to slidev in it` `so that the Whole `dvio'e may be adjusted laterally onthe footing' 38.

The position to be taken by the outer side `of the vval'l to be cast is` determined generally by tlievcarpenters line or cord which is fixed from the batter board which has been properly located on `or above the surface of the ground. Itivvill be understood of course that the footing 38 isgenerally` in a Iposition below the surface of the ground and therefore not readily accessible for continuous measurements or adjustments. A plumb bob dropped from the carpenters line to the footing 38 inthe usual Way may be employed to locate the line on the footing which the outer side `of the Wall to be cast shouldtake. The mem-e` bers 28 and 29 oflthe device may be positioned by the plumb bob by sliding the members 214 and 25 through the member 30 `Which is engaged `with the dowel pin 33.' When the members `28 and 29 have been brought to the proper position to fix the outer side of the Wall to `be cast, a blow ofa hammer or other deviceon the member 30 `"may deform itand the members 24andf25 in such a" Way asto hold the entire mechanism in the posif tion determined by the` plumb line. The result of- `this `pinching and positioning` blow is illustrated end of the device, as shown inFig. 3, and the i the ends: of Istrips yis,4 i221 one are traded-inermi?. 55"

eguivalentmembers 218 and 29 at the right hand` sidepf the `device is predetermined to equal the thickness ofthe Wall to be cast.` Thus, one form member 34 to determine one side of the Wallto be cast may be placed against the position mem- 'bers 28 and`29 and the opposite form` member 35` may be placed against the other or opposite members 28 and 29, and when the cement is cast the YWall Will be properly aligned or `positiened and of the proper predetermined thickness. Any usual or desired reinforcing means may be inserted between the form walls. At the ends of the tongues 20, the upwardly turned members 2| may be positioned from the members 28 'and 29 a suicient distance to receive between the mem- 34 but also a blocking or positioning longitudinal member 35 which may be of 2 x 4 or other standard size. A nail 31 may be driven through the hole 22 in the upwardly turned member 2| at each end of the device to hold the frame together and in proper position. By this means, it will be seen that the base of the wall frame may be properly positioned on the footing 34. The upwardly extending ends of the form members 34 and 35 may also be brought into proper relation in any suitable way such as by carpenters line and batter board on or above the surface of the ground.

Thus, when the form members 34 and 35 are held in position on the footing 38 and are then erected vertically, the position of the entire wall will deiinitely be determined. Heretofore it has been customary to rely upon so positioning the upper ends of the form members. While .this may be sufficient in some instances it sometimes becomes necessary to definitely and accurately position the entire wall not merely at the .top but at the botto-m. This may be especially important when 4the wall is being placed'on a property line. It may be necessary to keep the line Within oneeighth of an inch of accuracy not merely at the top but also atthe bottom.' It will be seen that the present device is admirably adapted to accomplish this purpose.y

As 'indicated in Fig. 3, .the hole 32 in the sliding member 3U is practically .the same size as the cross section of the dowel pin 33 and this'may be a preferable arrangement and may be convenient at times. The dowel pins 33, however, are not always the same size nor are they made with great care as to accuracy. It may be desirable,

. bers 2| and 28, 29 not only the frame Wall board therefore, to have a device with a hole which maybe capable of adapting itself to different sizes and irregularities of dowel pins 33. It may be, therefore, instead of cutting the simple hole indicated in Figs. 3 and 4 to provide one or another ofthe openings indicated in Figs. 7, 8 and 9. In

Fig. 7 is shown an oval hole 4E) joined by transverse cuts 4l so that ythe dowel pin may be forced through .the hole 43 and cause the metal to deform or be relieved at the cuts 4I so as to rightly clasp the dowel pin 33, In Fig. 8 a similar oval hole 40' is shown with transverse cuts 42 at the ends of the hole 4l! so as .to accommodate dowel pins of varying sizes and shapes. In Fig. 9 the hole dois provided with a serrated edge made up of serrations or Vteeth 43 to allow engagement with dowel pins of varying sizes.

In Figs. 10 and 11 is shown an optional arrangement which omits the sliding member 3i). lThe aligning member blank substitutes for the members 24 and 25 similar cut-out members 44 and 45, the edges of which are slightly separated and provided withserrations or teeth 45. The members 44 and 45 may be .turned upwardly as indicated at the left` in Fig. l1. In such position the device may be placed over the dowel pin 33 and may beout of actual engagement therewith. In thisiposition the device may be shifted laterally on the footing 38 until it reaches the desired position when a blow of` a hammer or other device on `the serrated members 44 and 45 at the lsides of the dowel pin 33 may cause the serrations 46 to take the position indicated at the right hand side of Fig. 11 and thus hold the device against lateral movement on the dowel pin 33. It will be understood of course that the other members, as shown in Fig. 3, such as 28, 29, 20 and 2l, will be present and employed as indicated above.

In Figs. 12, 13 and 14 is shown an optional form of construction. A strip of metal as indicated in Fig. l5 may be cut so as .to allow the tongues 28a to be turned upwardly and then the entire edge 50 between .the tongues 28a may be turned vupward and the edges of -the strips 28a lie against the base 5l of the strip which is provided at its ends with extending tongues 20a whose .terminal ends 2 la are turned upwardly as indicated in Figs. 12 and 13. A separate strap of metal 52 may be shaped to loosely surround and slide upon the members 50, 5I as indicated in Fig. 16. The projecting ends 53 of .the member 52 are perforated to engage the dowel pin 33. The device then may be properly adjusted on the footing 38 and a chisel or other device placed in the slo-t'54 provided in the sliding member 52. A blow onthe chisel may then deform the device as indicatedr in Fig. .ll'and hold the mechanism in the proper adjusted position to form the necessary seat at the proper place for the walls of the form. i

The holding members such as 2| and 28 have members 36 may be omitted When desired and the distance between the members 2| and 28 may be only suflicient .to receive the edge of the form boards 34 and 35 without additional bracing.

While the device has been described as being' made from a strip or sheet of metal it will be understood that it or some parts of it may be cast or otherwise produced.

Changes and variations in the structure may be made without departing from .the invention.
